6f7fc2204b NodeMonitor: Added B_WATCH_CHILDREN flag.
* Added a directory argument for notify_{stat/attribute}_changed().
* This allows to watch only a directory, and get the notifications for
  all of its files, not just add/remove entry notifications.

e3616ca108 system: Provide elf.h to applications
Make a version of elf.h (assembled from the private header files
elf_common.h, elf32.h and elf64.h, and including Haiku's extensions for
C++) available to applications ported from UNIX.

81e04d7b97 kernel: Remove cpu_info::load
This field forces kernel to track each CPU load all the time. It is not
a problem with the current scheduler on a multicore systems, but on
single core machnies or with any other future scheduler this field may
become just an unnecessary burden. It isn't difficult for an application
to compute CPU load by itself when it needs it.

f8da8f3477 ARM: Be aware of ARMEL and ARMEL
* My BeagleBone gcc defines __ARMEL__ but not
  __ARM__ which breaks the native tool builds
* As ARM was originally Little Endian, we assume
  __ARM__ means as such.
* Look for Big Endian ARM and define the needed big
  endian preprocessors

77ea49f4f2 Adjust debug API to address some x86-64 concerns.
- The argument buffer contained in the debug_{pre,post}_syscall message structures wasn't large enough to accomodate all
arguments for some syscalls on x86-64, which could potentially have led to kernel memory corruption when using syscall
tracing via the debug API. As such, enlarge it to accomodate 64-bit platforms as well.

- Adjust TeamDebugger/SyscallInfo to discriminate the target architecture and read the arguments when trapping console
output. Gets the latter working on x86-64.

5d0a1da8bf libroot: make all areas executable for old binaries
* If at least one image is either B_HAIKU_ABI_GCC_2_ANCIENT or
   B_HAIKU_ABI_GCC_2_BEOS almost all areas are marked as executable.
 * B_EXECUTE_AREA and B_STACK_AREA are made public. The former is enforced since
   the introduction of DEP and apps need it to correctly set area protection.
   The latter is currently needed only to recognize stack areas and fix their
   protection in compatibility mode, but may also be useful if an app wants
   to use sigaltstack from POSIX API.

bf65fc1dfe vm: remove B_RANDOMIZED_IMAGE_ADDRESS address specification
This address specification is actually not needed since PIC images can be
located anywhere. Only their size is restriced but that is the compiler and
linker concern. Thanks to Alex Smith for pointing that out.

65ed4fa908 vm: implement B_RANDOMIZED_IMAGE_ADDRESS address specification
On some 64 bit architectures program and library images have to be mapped in
the lower 2 GB of the address space (due to instruction pointer relative
addressing). Address specification B_RANDOMIZED_IMAGE_ADDRESS ensures that
created area satisfies that requirement.

b3e4c67739 vm: implement B_RANDOMIZED_ANY_ADDRESS address specification
Randomized equivalent of B_ANY_ADDRESS. When a free space is found (as in
B_ANY_ADDRESS) the base adress is then randomized using _RandomizeAddress
pretty much like it is done in B_RANDOMIZED_BASE_ADDRESS.

f9bab525f6 vm: implement B_RANDOMIZED_BASE_ADDRESS address specification
B_RAND_BASE_ADDRESS is basically B_BASE_ADDRESS with non-deterministic created
area's base address.

Initial start address is randomized and then the algorithm looks for a large
enough free space in the interval [randomized start, end]. If it fails then
the search is repeated in the interval [original start, randomized start]. In
case it also fails the algorithm falls back to B_ANY_ADDRESS
(B_RANDOMIZED_ANY_ADDRESS when it is implemented) just like B_BASE_ADDRESS does.

Randomization range is limited by kMaxRandomize and kMaxInitialRandomize.

6e2f6d1ace Changed cookie type for get_next_area_info() to ssize_t.
The cookie is used to store the base address of the area that was just
visited. On 64-bit systems, int32 is not sufficient. Therefore, changed
to ssize_t which retains compatibility on x86 while expanding to a
sufficient size on x86_64.

4304bb9894 Added arch_cpu.cpp to the x86_64 build.
* Some things are currently ifndef'd out completely for x86_64 because
  they aren't implemented, there's a few other ifdef's to handle x86_64
  differences but most of the code works unchanged.
* Renamed some i386_* functions to x86_*.
* Added a temporary method for setting the current thread on x86_64
  (a global variable, not SMP safe). This will be changed to be done
  via the GS segment but I've not implemented that yet.

case.
* <OS.h>: Also handle __x86_64__.

24df65921b Merged signals-merge branch into trunk with the following changes:
* Reorganized the kernel locking related to threads and teams.
* We now discriminate correctly between process and thread signals. Signal
  handlers have been moved to teams. Fixes #5679.
* Implemented real-time signal support, including signal queuing, SA_SIGINFO
  support, sigqueue(), sigwaitinfo(), sigtimedwait(), waitid(), and the addition
  of the real-time signal range. Closes #1935 and #2695.
* Gave SIGBUS a separate signal number. Fixes #6704.
* Implemented <time.h> clock and timer support, and fixed/completed alarm() and
  [set]itimer(). Closes #5682.
* Implemented support for thread cancellation. Closes #5686.
* Moved send_signal() from <signal.h> to <OS.h>. Fixes #7554.
* Lots over smaller more or less related changes.

implemented as B_32_BIT_CONTIGUOUS when B_HAIKU_PHYSICAL_BITS > 32, though.

a608485f26 * Added new team flag B_TEAM_DEBUG_PREVENT_EXIT that prevents teams from exiting
via exit() (the calling thread will drop into the debugger instead).
* The DebugServer now uses this flag by default.
* Added TODO comment: the default debugger should already be able to set a flag
  like this in order to close a race condition between dropping a thread into
  the debugger and setting the flag.
* Cleaned up the debug_server sources a bit.
